After 5 minutes of playtime the game will stop responding to my keyboard and mouse and gets stuck on what ever action I'm doing. If I'm running forward then when it happens, I will continue running and can't stop or turn etc, as if the forward key is stuck down. This happens with any action, if I'm swinging my sword and it happens, my character will just stand there swinging until I Ctrl+Alt+Delete out of the game.

The game is not frozen though, it's still running, NPCs, enemies everything still normal, just lost all control.

This happened all of a sudden, used to run fine, I have not installed any new mods or software for some time, but I did get a windows update.

Other games and software run fine with no issues.

if you can, remove the last update, and see if the problem goes away.

If that doesn't help, try installing the klite basic codec pack. Be sure it is set to repair broken codecs, and ffdshow is set to ignore oblivion.

The installer says I already have Media Player Codec and should remove that first. Is that what I should do?

Also, I tried disabling sound in the ini. file and that stopped the crashing, so I guess it is sound related.

Thanks HeyYou, that solved my problem and also made it run a bit smoother.
